Purely Custom (mentioned above) has them and other cool stuff... BUT their shipping costs are outrageous.

That was pretty steep for a single headset screw. However for the things I'm thinking about, it seemed as reasonable as anything from ebay.

Thanks to all for the info. Now for a question. I've just a built a liquid blue Santa cruz Chameleon with ano red CK headset and Hope seatpost collar. Would it be too much to put ano red clamps and bar ends on as well? Especially for a poseur who can't ride?
